Currently we pin the GuC or HuC firmware image just before uploading.
Perma-pin during uC initialization instead and use the range reserved at
the top of the address space.
Moving the firmware resulted in needing to:
- use an additional pinning for the rsa signature which will be used
during HuC auth as addresses above GUC_GGTT_TOP do not map through GTT.
v2: Remove call to set to gtt domain
Do not restore fw gtt mapping unconditionally
Separate out pin/unpin functions and drop usage of pin/unpin
Use uc_fw init/fini functions to bind/unbind fw object
v3: Bind is only needed during xfer (Chris)
Remove attempts to bind outside of xfer (Chris)
Mark fw bind/unbind static

GuC related exported functions should start with "intel_guc_" prefix and
pass intel_guc as the first parameter since its GuC related. Current
guc_ggtt_offset() failed to follow this code convention and this is a
problem for future patches that needs to access intel_guc data to verify
the GGTT offset against the GuC WOPCM top.
This patch renames the guc_ggtt_offset to intel_guc_ggtt_offset and updates
the related code to pass intel_guc pointer to this function call, so that
we can have a unified coding style for GuC code and also enable the future
patches to get GuC related data from intel_guc to do the offset
verification. Meanwhile, this patch also moves the GUC_GGTT_TOP from
intel_guc_regs.h to intel_guc.h since it is not GuC register related
definition.
v8:
- Fixed coding style issues and moved GUC_GGTT_TOP to intel_guc.h (Sagar)
- Updated commit message to explain to reason and motivation to add
intel_guc as the first parameter of intel_guc_ggtt_offset (Chris)
